Item Food and nymph stage duration influence life table parameters of the predator Brontocoris tabidus (Heteroptera: Pentatomidae)(Biological Control, 2018-02) Campos, Juliana Mendonça; Medeiros, Rômulo Sátiro de; Pereira, Alexandre Igor Azevedo; Lemes, Pedro Guilherme; Barbosa, Leonardo Rodrigues; Serrão, José Eduardo; Zanuncio, José ColaFood type is important for mass rearing of Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae), which preys on Lepidoptera defoliators in eucalyptus plantations. The objective of this study was to evaluate the duration of nymph instars, reproduction and the life expectancy table of the predator B. tabidus fed with or without Eucalyptus cloeziana plants and Tenebrio molitor Linnaeus (Coleoptera: Tenebrionidae) in the field. Brontocoris tabidus females were separated into those with short (a) or long (b) instar durations. Life expectancy (ex) of B. tabidus females from nymphs with short stage duration, reared on E. cloeziana with prey was higher than those from long nymph stage with or without plant material. Feeding on plant material and/or prey changes life table parameters for the predator B. tabidus. Therefore, B. tabidus should be reared with prey and E. cloeziana to improve the mass production of this predator for biological control of defoliating caterpillars in eucalypt plantations.Item SP-index: The measure of the scientific production of researchers(Biochemical and Biophysical Research Communications, 2012-09-07) Dodson, M.V.; Duarte, Marcio de Souza; Dias, Luiz Antônio dos SantosAbility to assess how solidly one is participating in their research arena is a metric that is of interest to many persons in academia. Such assessment is not easily defined, and differences exist in terms of which metric is the most accurate. In reality, no single production metric exists that is easy to determine and acceptable by the entire scientific community. Here we propose the SP-index to quantify the scientific production of researchers, representing the product of the annual citation number by the accumulated impact factors of the journals whereby the papers appeared, divided by the annual number of published papers. This article discusses such a productivity measure and lends support for the development of unified citation metrics for use by all participating in science research or teaching.
